Description

[Detailed description of the invention] Liquid outlet adapted for providing lighting effects and/or illumination The invention relates to (but is not limited to) a liquid outlet. The body outlet may include a fountain nozzle, a domestic tap, a hose nozzle, and the like.

It is an object of the present invention that the fluid flow provides a source of illumination. It's about providing an outlet.

Regarding fountains, the illumination is generally hidden from view and the gushing water Illuminating such a fountain by reflection from an upwardly directed light source is publicly known. Although such lighting effects can be effective enough, the visual effects are arises from light reflected from the water toward the eye, and much of that light traverses the gushing water. available light is not used effectively as it is transmitted through or through Additionally, a light source must be placed around or in close proximity to the water jet. Therefore, from certain positions around the fountain, viewers will be dazzled by the light and the view of the fountain will be spoiled. This is often the case.

Several alternatives to traditional fountains have been proposed in the past, according to which water passes through the chamber and from there directly into the fountain stream, and the light enters the chamber. Light is projected from outside toward the exit. Such prior art is U.S. Patent No. 1.83. 9,994 and Budokaku Patent No. 1,187.8H. Ru. However, in each of these examples, the light source is external to the fluid stream and the light is , into the housing where the fluid flows towards the outlet. these The array is cool and bulky, and the light that enters the chamber and the light that passes through the chamber and exits. Significant optical losses due to transmission losses due to 1 reflection and diffraction dispersion between the transmission of The purpose of the present invention is to direct the light in such a way that maximum light input is achieved with minimum loss. The objective is to provide a liquid outlet that can be introduced into the fluid stream at the outlet.

In one embodiment, the invention provides substantially non-turbulent and/or low turbulent liquids. an outlet through which a flow can be formed at the outlet for a distance beyond the outlet a housing coupled to a liquid source having a liquid source and introducing light into the liquid stream at the outlet; A liquid outlet consisting of a light source and a liquid outlet.

In one preferred embodiment of the invention, the light source is arranged within the housing. , and supported within a holder in heat exchange relationship with the liquid flowing through the housing. It consists of a lamp.

According to a preferred feature of the invention, a light source is optically connected to the outlet.

According to a further advantageous feature of the above features, the lamp is arranged adjacent to the outlet. Ru.

According to a further advantageous feature of the invention, the light source is arranged at a distance from the outlet and the light guide The id provides an optical connection between the light source and the outlet.

Eliminating some of the above drawbacks with fountains, the fountain's fluid stream acts as a light guide. transmits light to a region where the fluid flow is substantially turbulent or dispersed, and the light observed by multiple variable refractions at the body/air and/or air/liquid interfaces. It is one aspect of the present invention to provide a means by which information can be communicated to a viewer.

Furthermore, the present invention provides a method for reflecting light by its surface at the point of collision of the logic stream. A hand that can illuminate a surface by directing a stream of liquid onto such a surface. Provide steps.

The principle on which each embodiment of the invention relies is that light is transferred from a high index medium to a low index medium. the angle of incidence is greater than or equal to the critical angle of those media, l, ) is related to the total internal reflection of light at the interface between the two media) , even if the angle of incidence is smaller than the critical angle, it will still enter the medium rather than passing through the interface. The reflection of light returning to the area also changes to some extent. These phenomena are shown in Figures 2a and 2, respectively. Illustrated in Figure b).

t± when light is projected from the light source onto the water stream 11 exiting from the nozzle 12.

Most of the light is completely reflected inward within the water column until a turbulence is introduced into the water column. , when the disturbance is introduced, t±, the light is emitted from the disturbed part of the water column. Forced to pass through the water column. As shown in Figure 1, the result is a boundary between water and air. as long as the field conditions are such that the total internally reflected light is transmitted through the water column. , the water column or fountain acts as a light guide. Furthermore, the fountain itself is the arrow in Figure 3. Due to the presence of foreign objects, bubbles, etc. in the water as indicated by mark A, It may become.

! $3 As shown in FIG. When struck, the impact area of the fountain is illuminated creating a spectacular display.

produced by light within the water column and its possible escape from it Spectacular visual effects are the objective of each of the embodiments described below.

The first embodiment shown in FIG. 4 is regulated by a tap 14 and has an outlet 16. It consists of a faucet 11 with an extended water supply nozzle 15. Inside the nozzle 15, Adjacent to outlet 1B is housed a lamp housing 17, which comprises a halogen quartz lamp. The transparent exterior of rung housing 17 supporting outlet 1B and adjacent outlet 1B The side end 19 passes from the nozzle 15 through the lamp housing 17 to the outlet 18. cavities in the liquid stream (which disperse the light from lamp 18 and Therefore, the light reaching the exit 1B is reduced. ) that turbulence occurs in relation to Hydraulically shaped to prevent. Additionally, the outside of the lamp or housing The ends are shaped to prevent such turbulence and the outer ends are fitted with condensing lenses. 19 will help concentrate the light coming out of the lamp housing, and , the lamp/λ housing 17 and the fluid flow are in a heat exchange relationship, so that the lamp - Sufficient cooling of the housing will be guaranteed. Lamp meeting housing 17 , with a reflective surface on the inside to maximize the light output towards the fluid outlet 16. The nozzle 15 may extend over its entire length and have a Considering the power cable, it is designed with a groove 20 that is opened in a position that is normally invisible. has been completed. The portion of the groove 20 adjacent to the lamp holder \Using 17 is located on the side surface. The size is increased, and the lamp 18 is replaced by combining the closing member 21. For this purpose, the rear of the lamp/Using is accessible. lamp 18 The lighting of is a control sensitive to the operation of the tap 14 which causes a water flow through the nozzle 15. This is done by means of a device or a water flow sensing member placed in the water flow.

When leaving such a fluid outlet, if the jet has an irregular surface, the inward Light emerges from the jet along its length where reflection is not total. This is it In addition to the aesthetic effect, this also makes the fluid flow more visible. This can be advantageous in cases of scarcity or when visibility of the fluid jet is desired. Ru. When a jet has a very smooth interface, it always The conditions for reflection are met, which disturbs the fluid flow or presents an impact on the surface. are doing.

In addition, although the flow appears to be smooth and normal, the continuity of the jet that is transmitting light is , moving rapidly through the jet over a very short distance, e.g. at right angles to the jet. When the light is interrupted by an object (for example, a piece of wire) that Radiating from the flow, this discontinuity becomes visible and appears as a speck of light. Ru. This discontinuity point moves along the jet with the velocity of the liquid in the jet, so this light The speckles appear to move along the jet, giving a spectacular effect. putter for a while Means may also be provided for breaking the continuity of such light transmitting jets in accordance with the .

If the flow appears to be smooth and normal, but the jet that is transmitting light is pointing downwards, the jet is As the velocity of the fluid increases due to gravity, the diameter of the jet decreases with the length of the jet The particles contained in the jet flow until the jet ruptures into droplets due to the cohesive force of the liquid molecules. A concentration of light occurs. In this region of the jet, the jet concentrates into a thin jet until just before it breaks. All the light that enters leaves the jet.

Gives a very bright effect by emitting strong radiation to the surrounding area.

However, if the fluid flowing out from the nozzle 15 contains colored, fluorescent or other Any particles of foreign matter of any nature or bubbles of air or gas may If this light hits the surface of the jet at an angle smaller than the critical angle, it will be visible to the eye. You will be able to understand.

In any of the above cases, i.e. irregular bright looking jet and smooth normal In the case of visible jets, the light is present within the jet. As a result, the container cannot be filled with such liquids. When filled with a jet, the light spreads inside the container, illuminating it from the inside and generally making it difficult to inspect. On the other hand, when a transparent container such as glass is filled from the nozzle, it is spectacular. effect is given.

The second embodiment of FIG. 5 has a nozzle 15 provided with an outlet 1B and a valve 14 Therefore, it relates to the faucet 11 that is operated. Intermediate chamber 22 connects the outlet of tap 14 and and the lower end of the nozzle 15 and has a window directed toward the lower end of the nozzle 15. It accommodates lamp l~Using 17. Lamp housing 17 is 7~loge The halogen lamp 18 is located inside the /\Using 17. is in a heat exchange relationship with the fluid within the inter-chamber 22 and directs light toward the lower end of the nozzle 15. ing. The inner surface of the nozzle 15 is smooth and coated with a reflective coating 23a. It is made to be more reflective. As in the first embodiment, operation of the lamp 18 is a switch associated with step 14, i.e. a pressure sensing or flow sensing switch in the water flow; Alternatively, this can be done via an electronic switching device. The inside of the nozzle is reflective. 1. Because the side walls are substantially parallel, and the side walls are substantially parallel. Nozzle 15 is lamp 1 8 and serves as a light guide providing an optical connection between outlet 16.

The third embodiment of FIG. Perspex-like over a significant portion of the distance between No. 5 except that it is formed of a tubular liner 23 formed of a transparent material. This embodiment relates to a water faucet having a similar form to the second embodiment shown in the figures. The outer surface of this liner The liner is spaced apart from the inner wall of the liner, and a gap 23b is formed between the two. Suitable sealing means 24 are provided at both ends of the air gap to prevent fluid from entering this gap. ing. The light from the lamp 18 is transmitted by the tubular liner and the water directed through it. The outlet 16 is optically connected to the outlet 16 by a light guide formed by the same. nozzle 15 The light passing through is partially reflected by the inner surface of the tubular liner 23 and partially reflected by the tubular liner 23. The incident light is refracted by the liner wall, and the part beyond this is incident on the outer surface of the tubular liner. A total white reflection occurs on the internal surface of the tubular liner when the angle is greater than the critical angle. Light that reflects from the surface hits the inner surface of the tubular liner again and is refracted and reflected. or cause total white reflection.

In this way, the tubular liner acts as a hollow light guide and guides it through the tubular liner. Light propagates through the walls of the tubular liner in the same manner as through the fluid in which it is exposed.

The tubular liner 23 is made of a transparent material with a lower refractive index than the material of the tubular liner 23. It may be coated with a material. By doing so, hollow light that does not depend on the existence of the void 23b We can also provide guidance.

Furthermore, the inner wall of the nozzle 15 between the chamber 22 and the outlet IB is provided with a When coated with a transparent material with a refractive index smaller than that of the fluid, the angle of incidence of the two lights becomes critical. As long as the angle is larger than the angle, the light from the light source 18 will be completely reflected by this surface and will pass through the fluid. You will be led to Exit 1B.

Another form of this embodiment is such that at least the free end of the liner is exposed. Contains an exit tubular liner, so that when the wood flows out of the nozzle, the end of the nozzle It may glow and cast some light on the outside of the water jet.

The fourth embodiment shown in FIG. 7 is a modified example of the second embodiment shown in FIG. The guide is a conventional flexible light guide made of glass #a male, synthetic am or fluid filled. It is housed in a conduit (groove) 26 inside the nozzle 15.

The groove 2B may be sealed to prevent water from entering inside.

If the conventional light guide is resistant to wood influence, the groove 26 is unnecessary. The outer end of the groove 26, which may be present, prevents turbulence and the like in the jet exiting from the outlet 1B. light emitted from the light guide 25. supporting a hydraulically shaped closure member to provide a focusing effect on the Ru.

The fifth embodiment of FIG. 8 is also a variation of the second embodiment of FIG. is supported within the nozzle by spacer elements 27 at intervals along its length. a clear water pipe extending between the ramp 18 (not shown) and the exit IG; It consists of a transparent rod 25. In this case, the transmission of light is between the material of the rod and the surrounding flow. The difference in refractive index with the body, for example in the case of perspex and water is based on the difference between l, 49 and 1.33.

A sixth embodiment, shown in Figures 9a and 9b, is approximately perpendicular to the longitudinal axis of the nozzle. a nozzle with an outlet 29 oriented in the direction of a corner and placed at some distance from the tap; 28. Nozzle 28 connects lamp housing 30 adjacent outlet 28. I support you.

Moreover, the lamp 31 is housed therein. The housing 30 has a window facing the exit 29. However, the remaining inner surface of the housing 30 is provided with reflective properties. All incident light onto it is directed towards the window and thus towards the jet 29. Lamp 31 operation The operation is performed by operating a tap in conjunction with the nozzle 28, or by using a flow control switch or a pressure sensor. water flow, pressure or This is done by a presence sensing electronic switch device. Electric power for lamp 31 The cable is housed in a groove 32 located within the nozzle, while the lamp fist housing The wall of the groove facing the ring 30 is designed to be easily accessible when replacing the lamp. A closure member is provided.

The seventh embodiment of FIG. 10 is a modified example of the sixth embodiment of FIG. 31 are supported at intervals within the nozzle 28 and are hydraulically shaped. It is housed within a housing 30. This lamp is placed in close proximity to the concave mirror 34. so that the light emitted from the lamp and incident on the mirror 34.

Directed to exit 29. The electric cable connected to the lamp 31 connects the nozzle 28. extend through the nozzle at some suitable invisible position, and open into the atmosphere. It is housed within a flexible conduit. The conduit 35 is flexible and connects directly to the atmosphere. Due to the presence or absence of fluid flow flowing through the nozzle 28, Easily eliminates pressure changes occurring within the housing 31 and the conduit, as well as changes caused by the light source. It can be adjusted to

The eighth embodiment of FIGS. 11a and 11b is similar to the sixth embodiment of FIG. Here is another modified example. The first form shown in FIG. Bar-shaped clear transparent light guide 38 supported by a pacer member (not shown) A diagonal reflective surface is formed on the outer edge of the light guide 3B. All the light reaching the end of the nozzle is reflected and directed toward the nozzle outlet 29. . The embodiment shown in FIG. 11b houses a conventional flexible light guide 3B within a sealed groove 38. I am accommodating. A plane or concave mirror is positioned adjacent the free end of the light guide 38. and directs all the light emitted from the light guide toward the nozzle outlet 23.

In this case as well, if the flexible light guide is not easily affected by fluid, @38 is not necessary.

The ninth embodiment of FIGS. 12a and 12b is guided by a nozzle 28. It consists of two configurations that use a fluid as a light transmission medium. The first shown in Figure 12a In this case, the inside of the nozzle 28 is made of perspex-like material. supports a tubular liner of clear transparent material, the outer wall of the liner is connected to the nozzle. 28, and both ends of the gap thus formed are sealed. Prevents water from entering. As in the third embodiment of FIG. Light from a placed lamp (not shown) passes through the nozzle and the water flowing through the tube. is guided to the outer end of the nozzle by a wall of wood. The outer end of the nozzle 28 is a concave mirror. , whose concave mirror directs all the light incident on it through the nozzle 28. I'm heading towards exit 28. In the case of the second form of this embodiment, the inner wall of the nozzle 28 is smooth and reflective.

The nozzle exit described so far can be of any shape, such as annular, oval, rectangular, or elongated. Thus, as shown in Figures 12c and 12d, In particular, certain embodiments have elongated slit-like outlets, e.g. as a faucet regulated by a tap or as a fountain display It may also be possible to produce water in sheet form, as used in Also in this case, the lamp housing 101 is in heat exchange relationship with the liquid and the light source 10 The light emitted from 7 is the liquid that enters the faucet from the inlet 100 and reaches the intermediate chamber 105. through the window 102 and toward the outlet 103 and directly into the fluid stream 104. indirectly into the fluid stream 104 through a nozzle inner wall that is made reflective and/or reflective. It will be destroyed.

The window 102 is provided with hydraulic pressure to prevent turbulent flow and cavitation associated therewith. However, it may be shaped scientifically.

If the dimensions of the intermediate chamber 105 are larger than the dimensions of the outlet 103, the intermediate chamber The velocity of the liquid in the chamber is small and hydraulically shaping the window is not always necessary. In this way, *1o2 is recessed and the window 102 is opened as shown in FIG. 12e. The liquid in the depression 10θ can cause a light concentration effect, and Even with this, sufficient cooling is still guaranteed.

and the concentration of light directed toward the nozzle exit is maximized.

Alternatively, one at or near the window 102 between the light source and the exit. or more prisms or optical gratings to eliminate such elongated nozzle exits. The sheets of water discharged from the mouth are the letters R (red) and Y (yellow) in Figure 12c.

■ Along the length of the exit in the same order as in the rainbow case, as shown by (purple) It can also contain different colors at different positions. Such a touch A tap or faucet or fountain is a "rainbow" tap, faucet or fountain, as appropriate. It can also be called a fountain.

Naturally, in order to arbitrarily combine the colors of the light guided within the jet, Color filters may be placed in the
